Description

【０００２】
【発明の属する技術分野】
【０００３】
本願発明は、建物の壁面に取り付けられてこれを保護するための壁面保護材に関するものである。
【従来の技術】
【０００４】
従来より、建物の壁面が、例えば壁面近くを通る人の靴が触れることで汚れるとか破損するのを防止して壁面を保護する意味から、壁面の床面近くの高さ位置に、該床面に沿って帯板状の壁面保護材を装着することが行われている。
【０００５】
この場合、壁面保護材は、壁面にビス等によって固定される取付基材と、壁面に固定された取付基材に対してその前面を覆うように着脱自在に装着される表面部材とで構成されるのが通例である。
【０００６】
そして、壁面保護材における上記取付基材に対する上記表面部材の装着構造としては、上記取付基材の上側縁部と下側縁部にそれぞれ受部を設ける一方、上記表面部材側には上記取付基材側の上下各縁部に対応するように、その上下両縁部にそれぞれ掛止部を設け、壁面に固定された上記取付基材への表面部材の装着に際しては、先ず、該取付基材の上側縁部に設けられた受部に上記表面部材側の上側の掛止部を掛止させ、次に上記表面部材の下側縁部側を上記取付基材側に押し付けて該表面部材の下側の掛止部を上記取付基材側の下側の受部に弾圧的に嵌合させて掛止するのが通例である。
【発明が解決しようとする課題】
【０００７】
ところで、上述のように、取付基材の受部に対して表面部材の掛止部を掛止させる装着構造においては、該受部と掛止部との掛止状態が適正でないと該表面部材にガタツキが生じ、壁面保護材の使用上における信頼性あるいは耐久性が損なわれるおそれがあるため、壁面保護材の施工に際しては受部と掛止部との掛止状態の管理が重要となる。
【０００８】
ところが、実際には、上記取付基材及び表面部材は通常、樹脂材の押し出し加工等によって製作されるが、その際、製作誤差が生じることは不可避であり、また壁面保護材が取り付けられる壁面側においても建物の施工上、その平滑度、平面度にバラツキが生じることは、程度の差はあれ、不可避である。従って、取付基材の受部と表面部材の掛止部との掛止状態の管理は非常に難しいものであり、壁面保護材の使用上の信頼性あるいは耐久性の確保という点において、改善すべき余地がある。
【０００９】
そこで本願発明は、取付基材と表面部材とで構成される壁面保護材において、高い信頼性と耐久性を実現することを目的としてなされたものである。
【課題を解決するための手段】
【００１０】
本願発明ではかかる課題を解決するための具体的手段として次のような構成を採用している。
【００１１】
即ち、建物の壁面５０に適宜の固定具４により固定される取付基材１と、該取付基材１の表面側を被覆するように該取付基材１に着脱自在に装着される表面部材２とを備えてなる壁面保護材において、上記取付基材１の縁部１ｂに該取付基材１の上記壁面５０への取付状態において該壁面５０との間に所定の嵌合隙間６を形成するように該取付基材１の面方向外方へ延出する受部１２を設ける一方、上記表面部材２側には上記取付基材１側の上記嵌合隙間部６にその開口端側から嵌入することで上記受部１２に掛止される掛止部２３を設けるとともに、上記表面部材２の基板部２４の自由状態における形状を、上記壁部５０の平面壁部５１に取り付けられるものにあっては上下方向に適宜湾曲した湾曲面状とし、上記壁部５０の隅壁部５２に取り付けられるものにあっては該隅壁部５２の屈曲角度よりも所定角度だけ大きな折曲角度をもつように設定したことを特徴としている。
【発明の効果】
【００１２】
本願発明にかかる壁面保護材によれば、上記表面部材２の基板部２４の自由状態における形状を、上記壁部５０の平面壁部５１に取り付けられるものにあっては上下方向に適宜湾曲した湾曲面状とし、上記壁部５０の隅壁部５２に取り付けられるものにあっては該隅壁部５２の屈曲角度よりも所定角度だけ大きな折曲角度をもつように設定しているので、壁面５０に予め固定された上記取付基材１に対して上記表面部材２を装着するに際して、該表面部材２の掛止部２３を上記嵌合隙間６に嵌合させてこれを上記取付基材１の受部１２に掛止させた状態においては、上記表面部材２の弾性変形に伴う弾性復元力によって上記第２の掛止部２３が上記受部１２側に常時付勢される。この結果、例え上記取付基材１あるいは表面部材２に製作誤差があっても、また上記壁面５０の平面度等にバラツキがあったとしても、これらに影響されることなく、上記表面部材２の掛止部２３は上記取付基材１の上記受部１２に常時押圧状態で接触することとなり、従って、該表面部材２にガタツキ等が発生することがなく、延いては、壁面保護材の使用上の信頼性あるいは耐久性が向上するものである。
【発明の実施の形態】
【００１３】
以下、本願発明を幾つかの好適な実施形態に基づいて具体的に説明する。
【００１４】
第１の実施形態
図１には、本願発明の第１の実施形態にかかる壁面保護材Ｚ１を壁面５０の平面壁部５１に取り付けた状態を示している。即ち、この壁面保護材Ｚ１は、該平面壁部５１の床面５３近くの部位を保護するためのものであって、所定長さの帯板状の平面形態をもち、平面壁部５１の床面５３近くの高さ位置において該床面５３に沿うように該平面壁部５１に延設配置されている。
【００１５】
上記壁面保護材Ｚ１は、図２及び図３に示すように、取付基材１と表面部材２及び端部材３とを備えて構成される。以下、これら各部材１，２，３の具体的構造をそれぞれ説明する。
【００１６】
Ａ：取付基材１
上記取付基材１は、樹脂材の押出成形により成形されるものであって、所定長さの帯板状の平面形態を有している。そして、この取付基材１は、その長辺側に位置する上下両縁部１ａ，１ｂのうち、上側縁部１ａには第１の受部１１を、下側縁部１ｂには第２の受部１２を、それぞれ形成するとともに、該両縁部１ａ，１ｂの内側に位置する基板部１０はこれを平板状に成形しており、該基板部１０を上記平面壁部５１に衝合させ且つビス、ボルト等の固定具４，４，・・によってこれを締着することで該平面壁部５１に固定されるようになっている。
【００１７】
上記第１の受部１１は、図３に示すように、上記取付基材１の上側縁部１ａを該取付基材１の表面１ｄ側に折曲偏位させたような断面形状をもつものであり、該取付基材１の裏面１ｅ側の面を後述する表面部材２の第１の掛止部２２に対する受面１１ａとするとともに、該受面１１ａはこれを外縁端から上記基板部１０に向かうに伴って上記裏面１ｅに接近する（換言すれば、平面壁部５１に接近する）傾斜面としている。従って、上記取付基材１をその表面１ｄ側から上記平面壁部５１に衝合させ、上記基板部１０を該平面壁部５１に締着固定した状態においては、上記第１の受部１１の受面１１ａは上記平面壁部５１から適宜離間し、これら両者間には楔状の断面形状をもつ嵌合隙間５が上記取付基材１の長辺方向の全長にわたって形成されることになる。
【００１８】
上記第２の受部１２は、特許請求の範囲中の「受部１２」に該当するものであって、図３に示すように、上記取付基材１の下側縁部１ｂを該取付基材１の表面１ｄ側に折曲偏位させたような断面形状をもつものであり、該取付基材１の表面１ｄ側の面はこれを円弧面として後述する表面部材２の第２の掛止部２３の弾圧係入時の案内面１２ａとして機能させるようになっている。また、上記第２の受部１２の上記取付基材１の裏面１ｅ側の面は、後述する表面部材２の第２の掛止部２３に対する受面１２ｂとして機能するものであって、上記取付基材１の面方向に略平行な平面とされている。従って、上記取付基材１をその表面１ｄ側から上記平面壁部５１に衝合させ、上記基板部１０を該平面壁部５１に締着固定した状態においては、上記第２の受部１２の受面１２ｂは上記平面壁部５１から適宜離間し、これら両者間には略矩形の断面形状をもつ嵌合隙間６が上記取付基材１の長辺方向の全長にわたって形成されることになる。
【００１９】
Ｂ：表面部材２
上記表面部材２は、上記取付基材１と同様に、樹脂材の押出成形により成形されるものであって、所定長さの帯板状の平面形態を有している。そして、この表面部材２は、上記取付基材１の表面１ｄ側にこれを覆うようにして取り付けられるものであって、平板状の基板部２４と該基板部２４の上下両縁部に連続する上側覆部２５と下側覆部２６とを備えている。尚、上記各覆部２５，２６は、上記表面部材２を上記取付基材１側に取り付けた状態において、該取付基材１の上下両端部を覆って美観性を確保するためのものであって、それぞれ裏面２ｄ側に向けて湾曲する断面形状を有している。
【００２０】
さらに、上記表面部材２の裏面２ｄで且つ上記上側覆部２５及び下側覆部２６の近傍位置には、それぞれ第１の掛止部２２と第２の掛止部２３が設けられている。
【００２１】
上記第１の掛止部２２は、特許請求の範囲中の「掛止部２２」に該当するものであって、上記表面部材２の裏面２ｄから立ち上がり且つその先端部を該表面部材２の平面方向内側に向けて略Ｌ字状に折曲した略鉤状の断面形状をもち、上記表面部材２の長辺方向の全長にわたって設けられている。また、この第１の掛止部２２の先端部の内側面（裏面１ｅ寄りの面）２２ａは上記取付基材１の第１の受部１１の受面１１ａに掛止される掛止面２２ａとなるものであって、上記取付基材１の第１の受部１１における受面１１ａに対応するように該受面１１ａと同方向に傾斜する傾斜面とされている。
【００２２】
尚、この実施形態においては、上述のように、上記取付基材１の第１の受部１１における受面１１ａと上記表面部材２の第１の掛止部２２における掛止面２２ａの双方を傾斜面としているが、かかる構成に限定されるものではなく、これら両者のうちの少なくとも何れか一方が傾斜面とされていれば、後述する如く所期の目的は達せられるものである。
【００２３】
上記第２の掛止部２３は、特許請求の範囲中の「掛止部２３」に該当するものであって、上記第１の掛止部２２に対向するように、上記表面部材２の裏面２ｄから立ち上がり且つその先端部を該表面部材２の平面方向内側に向けて略Ｌ字状に折曲した略鉤状の断面形状をもち、上記表面部材２の長辺方向の全長にわたって設けられている。
【００２４】
さらに、上記基板部２４の裏面側には、上下一対のリブ２７，２７が上記表面部材２の長辺方向の全長にわたって設けられている。このリブ２７は、これが上記表面部材２の基板部２４の裏面と上記取付基材１の表面１ｄとの間に跨がって配置されることで該基板部２４の撓曲変形を防止するためのものであり、従って、このリブ２７はこの実施形態のように上記表面部材２側に設けることに限定されるものではなく、該表面部材２と上記取付基材１の何れの側にも設けることができるものである。
【００２５】
尚、上記表面部材２に設けられた上記上下一対の覆部２５，２６と上記第１の掛止部２２及び第２の掛止部２３は、該表面部材２の裏面２ｄからの突出高さが略同一に設定されるとともに、これらの突出高さは上記一対のリブ２７，２７の突出高さよりも上記取付基材１の厚さ寸法だけ大きな値とされる。
【００２６】
さらに、この実施形態においては、上記表面部材２の基板部２４を図３に実線図示するように平面状に形成するのではなく、図３に鎖線図示（符号２′で示す部分を参照）するように、該表面部材２を上記取付基材１側に取り付ける以前の自由状態においては上下方向に適宜湾曲した湾曲面状となるようにその製作時の形状を設定している。
【００２７】
Ｃ：端部材３
上記端部材３は、図１及び図２に示すように、壁面保護材Ｚ１の長辺方向両端部にそれぞれ設けられるものであって、上記取付基材１に上記表面部材２を取り付けた状態においてその両端部を覆蓋して該壁面保護材Ｚ１の美観性を確保するためのものであって、本体部３１の内側に上下一対の接続部材３２，３２を突設して構成される。
【００２８】
Ｄ：壁面保護材Ｚ１の取付作業等
続いて、上記の如く構成された壁面保護材Ｚ１を壁面５０の平面壁部５１に取り付ける場合の作業手順等について説明する。
【００２９】
壁面保護材Ｚ１の平面壁部５１への取付作業に際しては、先ず、上記取付基材１を、固定具４，４，・・を用いて上記平面壁部５１の所定高さ位置に固定する。この取付基材１の固定状態においては、上記第１の受部１１と上記平面壁部５１との間には上方に開口する上記嵌合隙間５が、また上記第２の受部１２と平面壁部５１との間には下方に開口する嵌合隙間６が、それぞれ該取付基材１の長辺方向の全長にわたって形成される。
【００３０】
次に、上記表面部材２を、上記取付基材１に対してその斜め上方側から、且つその下側縁部２ｂ側を手前に引いた傾斜状態で当てがい、該表面部材２の上側縁部２ａ側に設けられた上記第１の掛止部２２を上記嵌合隙間５に対してその上方側から嵌入させ、該第１の掛止部２２を上記取付基材１側の上記第１の受部１１に掛止させる。
【００３１】
この場合、該第１の掛止部２２の上記嵌合隙間５への嵌合度合いの進行に伴って、第１の掛止部２２の掛止面２２ａが上記受部１１の受面１１ａに係合し、該第１の掛止部２２はこれら両面２２ａ，１１ａの傾斜面による案内作用を受けて上記取付基材１の受部１１に接触したまま上記平面壁部５１側に移動され、該平面壁部５１に押し付けられることになる。この結果、例え上記取付基材１あるいは表面部材２に製作誤差があっても、また上記平面壁部５１の平面度等にバラツキがあったとしても、上記表面部材２の第１の掛止部２２は、上記平面壁部５１と上記取付基材１の受部１１の双方によって確実に挟持される。
【００３２】
次に、上記表面部材２の下側縁部２ｂ側を上記取付基材１側に取り付けるが、この場合、該表面部材２の上記基板部２４が湾曲形状とされていること、及び上記第２の掛止部２３が上記取付基材１側の上記第２の受部１２の案内面１２ａ上に位置していることから、作業者は上記表面部材２の下側縁部２ｂ寄り部分を上記平面壁部５１側に向かって押し付けることになる。この押圧力を受けて上記基板部２４が上記平面壁部５１に接近するように弾性変形するとともに、上記第２の掛止部２３も上記案内面１２ａの案内作用によって下方側へ弾性的に撓曲変形し、該第２の掛止部２３は上記案内面１２ａを乗り越えた時点で該第２の掛止部２３自身の弾性復元力によって上記第２の受部１２に掛止され、その離脱が阻止される。このように第２の掛止部２３が上記第２の受部１２に掛止された状態においては、上記基板部２４の弾性復元力が働き、該第２の掛止部２３は上記第２の受部１２側に所定の付勢力で押圧付勢される。この結果、例え上記取付基材１あるいは表面部材２に製作誤差があっても、また上記平面壁部５１の平面度等にバラツキがあったとしても、これらに影響されることなく、上記第２の掛止部２３は上記取付基材１の上記第２の受部１２に常時押圧状態で接触することになる。
【００３３】
このように、上記表面部材２を上記取付基材１に取り付けた状態においては、該表面部材２の上側縁部２ａ側においてはその第１の掛止部２２が上記平面壁部５１と上記取付基材１の受部１１の双方によって確実に挟持され、また該表面部材２の下側縁部２ｂ側においては上記第２の掛止部２３が上記取付基材１の上記第２の受部１２に常時押圧状態で接触することで、該表面部材２の上記取付基材１に対する取付状態が適正に維持され、該表面部材２にガタツキ等が発生するのが確実に防止され、延いては、壁面保護材Ｚ１の使用上の信頼性あるいは耐久性が向上することになるものである。
【００３４】
尚、上記各端部材３，３は、上記取付基材１に対して上記表面部材２を取り付けた後において、該表面部材２の両端面２ｅ，２ｅ側に、上記接続部材３２を嵌挿することで取り付けられる。
【００３５】
第２の実施形態
図４には、本願発明の第２の実施形態にかかる壁面保護材Ｚ２を壁面５０の隅壁部５２（即ち、左右の平面壁部５１，５１が所定の角度もって屈曲状態で連続する部分）に取り付けた状態を示している。即ち、この壁面保護材Ｚ２は、該隅壁部５２の床面５３近くの部位を保護するためのものであって、略Ｌ字状に折曲した折曲板形態をもち、隅壁部５２の床面５３近くの高さ位置から所定高さ位置までの範囲にわたって延設配置されている。
【００３６】
上記壁面保護材Ｚ２は、図５及び図６に示すように、取付基材１と表面部材２及び端部材３とを備えて構成される。以下、これら各部材１，２，３の具体的構造をそれぞれ説明する。
【００３７】
Ａ：取付基材１
上記取付基材１は、樹脂材の押出成形により成形されるものであって、所定長さの折曲板状の形態を有している。そして、この取付基材１は、その長辺側に位置する両縁部１ａ，１ｂのうち、右側縁部１ａには第１の受部１１を、左側縁部１ｂには第２の受部１２を、それぞれ形成するとともに、該両縁部１ａ，１ｂの内側に位置する折曲板状部分を基板部１０としており、該基板部１０を上記隅壁部５２に衝合させ且つビス、ボルト等の固定具４，４，・・によってこれを締着することで該隅壁部５２に固定されるようになっている。
【００３８】
上記第１の受部１１は、図６に示すように、上記取付基材１の右側縁部１ａを該取付基材１の表面１ｄ側に折曲偏位させたような断面形状をもつものであり、該取付基材１の裏面１ｅ側の面を後述する表面部材２の第１の掛止部２２に対する受面１１ａとするとともに、該受面１１ａはこれを外縁端から上記基板部１０に向かうに伴って上記裏面１ｅに接近する（換言すれば、隅壁部５２に接近する）傾斜面としている。従って、上記取付基材１をその表面１ｄ側から上記隅壁部５２に衝合させ、上記基板部１０を該隅壁部５２に締着固定した状態においては、上記第１の受部１１の受面１１ａは上記隅壁部５２から適宜離間し、これら両者間には楔状の断面形状をもつ嵌合隙間５が上記取付基材１の長辺方向の全長にわたって形成されることになる。
【００３９】
上記第２の受部１２は、特許請求の範囲中の「受部１２」に該当するものであって、図６に示すように、上記取付基材１の左側縁部１ｂを該取付基材１の表面１ｄ側に折曲偏位させたような断面形状をもつものであり、該取付基材１の表面１ｄ側の面はこれを円弧面として後述する表面部材２の第２の掛止部２３の弾圧係入時の案内面１２ａとして機能させるようになっている。また、上記第２の受部１２の上記取付基材１の裏面１ｅ側の面は、後述する表面部材２の第２の掛止部２３に対する受面１２ｂとして機能するものであって、上記取付基材１の面方向に略平行な平面とされている。従って、上記取付基材１をその表面１ｄ側から上記隅壁部５２に衝合させ、上記基板部１０を該隅壁部５２に締着固定した状態においては、上記第２の受部１２の受面１２ｂは上記隅壁部５２から適宜離間し、これら両者間には略矩形の断面形状をもつ嵌合隙間６が上記取付基材１の長辺方向の全長にわたって形成されることになる。
【００４０】
Ｂ：表面部材２
上記表面部材２は、上記取付基材１と同様に、樹脂材の押出成形により成形されるものであって、所定長さの折曲板状の形態を有している。そして、この表面部材２は、上記取付基材１の表面１ｄ側にこれを覆うようにして取り付けられるものであって、折曲板状の基板部２４と該基板部２４の左右両縁部に連続する右側覆部２５と左側覆部２６とを備えている。尚、上記各覆部２５，２６は、上記表面部材２を上記取付基材１側に取り付けた状態において、該取付基材１の左右両端部を覆って美観性を確保するためのものであって、それぞれ裏面２ｄ側に向けて湾曲する断面形状を有している。
【００４１】
さらに、上記表面部材２の裏面２ｄで且つ上記右側覆部２５及び左側覆部２６の近傍位置には、それぞれ第１の掛止部２２と第２の掛止部２３が設けられている。
【００４２】
上記第１の掛止部２２は、上記表面部材２の裏面２ｄから立ち上がり且つその先端部を該表面部材２の平面方向内側に向けて略Ｌ字状に折曲した略鉤状の断面形状をもち、上記表面部材２の長辺方向の全長にわたって設けられている。また、この第１の掛止部２２の先端部の内側面（裏面１ｅ寄りの面）２２ａは上記取付基材１の第１の受部１１の受面１１ａに掛止される掛止面２２ａとなるものであって、上記取付基材１の第１の受部１１における受面１１ａに対応するように該受面１１ａと同方向に傾斜する傾斜面とされている。
【００４３】
尚、この実施形態においては、上述のように、上記取付基材１の第１の受部１１における受面１１ａと上記表面部材２の第１の掛止部２２における掛止面２２ａの双方を傾斜面としているが、かかる構成に限定されるものではなく、これら両者のうちの少なくとも何れか一方が傾斜面とされていれば、後述する如く所期の目的は達せられるものである。
【００４４】
上記第２の掛止部２３は、特許請求の範囲中の「掛止部２３」に該当するものであって、上記第１の掛止部２２に対向するように、上記表面部材２の裏面２ｄから立ち上がり且つその先端部を該表面部材２の平面方向内側に向けて略Ｌ字状に折曲した略鉤状の断面形状をもち、上記表面部材２の長辺方向の全長にわたって設けられている。
【００４５】
さらに、上記基板部２４の裏面側には、複数のリブ２７，２７，・・が上記表面部材２の長辺方向の全長にわたって設けられている。このリブ２７は、これが上記表面部材２の基板部２４の裏面と上記取付基材１の表面１ｄとの間に跨がって配置されることで該基板部２４の撓曲変形を防止するためのものであり、従って、このリブ２７はこの実施形態のように上記表面部材２側に設けることに限定されるものではなく、該表面部材２と上記取付基材１の何れの側にも設けることができるものである。
【００４６】
尚、上記表面部材２に設けられた上記左右一対の覆部２５，２６と上記第１の掛止部２２及び第２の掛止部２３は、該表面部材２の裏面２ｄからの突出高さが略同一に設定されるとともに、これらの突出高さは上記一対のリブ２７，２７の突出高さよりも上記取付基材１の厚さ寸法だけ大きな値とされる。
【００４７】
さらに、この実施形態においては、上記表面部材２の基板部２４を図３に実線図示するように上記隅壁部５２の屈曲角度に対応した折曲角度に形成するのではなく、図３に鎖線図示（符号２′で示す部分を参照）するように、該表面部材２を上記取付基材１側に取り付ける以前の自由状態において上記隅壁部５２の屈曲角度よりも所定角度だけ大きな折曲角度をもつようにその製作時の形状を設定している。
【００４８】
Ｃ：端部材３
上記端部材３は、図４及び図５に示すように、壁面保護材Ｚ２の長辺方向両端部にそれぞれ設けられるものであって、上記取付基材１に上記表面部材２を取り付けた状態においてその両端部を覆蓋して該壁面保護材Ｚ２の美観性を確保するためのものであって、本体部３１の内側に上下一対の接続部材３２，３２を突設して構成される。
【００４９】
Ｄ：壁面保護材Ｚ２の取付作業等
続いて、上記の如く構成された壁面保護材Ｚ２を壁面５０の隅壁部５２に取り付ける場合の作業手順等について説明する。
【００５０】
壁面保護材Ｚ２の隅壁部５２への取付作業に際しては、先ず最初に、上記取付基材１を、固定具４，４，・・を用いて上記隅壁部５２の所定高さ位置に固定する。この取付基材１の固定状態においては、上記第１の受部１１と上記隅壁部５２との間には右側に開口する上記嵌合隙間５が、また上記第２の受部１２と隅壁部５２との間には左側に開口する嵌合隙間６が、それぞれ該取付基材１の長辺方向の全長にわたって形成される。
【００５１】
次に、上記表面部材２を、上記取付基材１に対して右側側方から、且つその左側縁部２ｂを若干手前に引いた傾斜状態で当てがい、該表面部材２の右側縁部２ａ側に設けられた上記第１の掛止部２２を上記嵌合隙間５に対してその右側方から嵌入させ、該第１の掛止部２２を上記取付基材１側の上記第１の受部１１に掛止させる。
【００５２】
この場合、上記第１の掛止部２２の上記嵌合隙間５への嵌合度合いの進行に伴って、第１の掛止部２２の掛止面２２ａが上記受部１１の受面１１ａに係合し、該第１の掛止部２２はこれら両面２２ａ，１１ａの傾斜面による案内作用を受けて上記取付基材１の受部１１に接触したまま上記隅壁部５２側に移動され、該隅壁部５２に押し付けられることになる。この結果、例え上記取付基材１あるいは表面部材２に製作誤差があっても、また上記隅壁部５２の平面度等にバラツキがあったとしても、上記表面部材２の第１の掛止部２２は、上記隅壁部５２と上記取付基材１の受部１１の双方によって確実に挟持される。
【００５３】

However, at this time, a manufacturing error is unavoidable, and the wall surface on which the wall protection material is mounted is unavoidable. However, it is inevitable that the smoothness and the flatness of the building vary in the construction of the building, although the degree of the difference varies. Therefore, it is very difficult to control the hooking state between the receiving portion of the mounting base material and the hooking portion of the surface member, and it is necessary to improve the reliability or durability in using the wall protection material. There is room to be done.
[0009]
Therefore, the present invention has been made for the purpose of realizing high reliability and durability in a wall surface protection material composed of a mounting base material and a surface member.

【The invention's effect】
[0012]
According to the wall protection material according to the present invention, The shape of the surface member 2 in the free state of the substrate portion 24 is a curved surface that is appropriately curved in the up-down direction when the surface portion 2 is attached to the flat wall portion 51 of the wall portion 50. In the one attached to the part 52, since it is set to have a bending angle larger by a predetermined angle than the bending angle of the corner wall part 52, When the surface member 2 is mounted on the mounting base material 1 previously fixed to the wall surface 50, the engaging portion 23 of the surface member 2 is fitted into the fitting gap 6, and this is fitted to the mounting base material. In a state where the second hooking portion 23 is hooked on the first receiving portion 12, the second hooking portion 23 is constantly urged toward the receiving portion 12 by an elastic restoring force caused by the elastic deformation of the surface member 2. As a result, even if there is a manufacturing error in the mounting base material 1 or the surface member 2, and even if the flatness of the wall surface 50 fluctuates, without being affected by these, the surface member 2 is not affected. The hooking portion 23 always comes into contact with the receiving portion 12 of the mounting substrate 1 in a pressed state, so that the surface member 2 does not rattle or the like, and the use of the wall protection material is extended. The above reliability or durability is improved.

As shown in FIGS. 4 and 5, the end members 3 are provided at both ends in the long-side direction of the wall surface protection material Z2, and in a state where the surface member 2 is mounted on the mounting base material 1. It is for covering the both ends to secure the aesthetics of the wall surface protection material Z2, and is configured by projecting a pair of upper and lower connection members 32, 32 inside the main body 31.
[0049]
D: Installation work of wall protection material Z2
Next, a description will be given of an operation procedure and the like when the wall protection material Z2 configured as described above is attached to the corner wall portion 52 of the wall surface 50.
[0050]
In the work of attaching the wall surface protecting material Z2 to the corner wall portion 52, first, the mounting base material 1 is fixed to a predetermined height position of the corner wall portion 52 by using the fixtures 4, 4,. I do. In the fixed state of the mounting base 1, the fitting gap 5 opening to the right is provided between the first receiving portion 11 and the corner wall portion 52, and the second receiving portion 12 and the corner A fitting gap 6 opening to the left is formed between the wall 52 and the entire length of the mounting substrate 1 in the long side direction.
[0051]
Next, the surface member 2 is applied to the mounting base 1 from the right side and in an inclined state in which the left edge 2b is pulled slightly forward, and the right edge 2a side of the surface member 2 is applied. The first engaging portion 22 provided on the mounting base 1 is fitted into the fitting gap 5 from the right side, and the first engaging portion 22 is attached to the first receiving portion on the mounting base 1 side. Hang it on 11.
[0052]
In this case, as the degree of fitting of the first hooking portion 22 into the fitting gap 5 progresses, the hooking surface 22a of the first hooking portion 22 moves to the receiving surface 11a of the receiving portion 11. The first hooking portion 22 is guided by the inclined surfaces of both surfaces 22a and 11a and is moved toward the corner wall portion 52 while being in contact with the receiving portion 11 of the mounting base material 1, It will be pressed against the corner wall 52. As a result, even if there is a manufacturing error in the mounting base material 1 or the surface member 2, and even if the flatness or the like of the corner wall portion 52 varies, the first hooking portion of the surface member 2 does not matter. 22 is securely held by both the corner wall portion 52 and the receiving portion 11 of the mounting base material 1.
[0053]
Next, the left edge 2b side of the surface member 2 is attached to the mounting base 1 side. In this case, the bending angle of the substrate portion 24 of the surface member 2 is larger than the bending angle of the corner wall portion 52. Is also set to a large angle, and since the second hooking portion 23 is located on the guide surface 12a of the second receiving portion 12 on the side of the mounting base 1, the worker can The portion near the left edge 2b of the surface member 2 is pressed toward the corner wall 52 side. Under the pressing force, the substrate portion 24 is elastically deformed so as to approach the corner wall portion 52, and the second hooking portion 23 is also elastically bent outward by the guide action of the guide surface 12a. The second hook 23 is deformed and is hooked on the second receiving portion 12 by the elastic restoring force of the second hook 23 when the second hook 23 gets over the guide surface 12a. Will be blocked. In the state where the second hooking portion 23 is hooked on the second receiving portion 12 as described above, the elastic restoring force of the substrate portion 24 works, and the second hooking portion 23 is moved by the second hooking portion 23. Is pressed and urged toward the receiving portion 12 by a predetermined urging force. As a result, even if there is a manufacturing error in the mounting base material 1 or the surface member 2, and even if the flatness or the like of the corner wall portion 52 has a variation, the second base material is not affected by the variation. Is in constant contact with the second receiving portion 12 of the mounting base 1 in a pressed state.
[0054]
As described above, when the surface member 2 is mounted on the mounting base material 1, on the upper edge portion 2 a side of the surface member 2, the first hook portion 22 is connected to the corner wall portion 52 by the mounting member 1. Both of the receiving portions 11 of the base material 1 are securely held, and the second hook portion 23 is provided on the lower edge portion 2b side of the surface member 2 by the second receiving portion of the mounting base material 1. When the surface member 2 is in constant contact with the mounting member 1, the state of attachment of the surface member 2 to the mounting substrate 1 is properly maintained, and the occurrence of rattling or the like on the surface member 2 is reliably prevented, and Thus, the reliability or durability in use of the wall protection material Z2 is improved.
[0055]
After attaching the surface member 2 to the mounting base 1, the end members 3 and 3 are fitted with the connection members 32 on both end surfaces 2e and 2e of the surface member 2. It is attached by that.
